Patrick is Chair of TDUK and UK Managing Director at INTERA. Over his career his primary work has been in multi-disciplinary infrastructure projects, bringing a keen eye for added value in planning stages drawing on extensive knowledge and background in engineering geology and geotechnical engineering. He brings an additional international perspective to TDUK through experience from extended periods in the Asia Pacific region blended with work in the UK on projects including the London 2012 Olympic Park Regeneration and Crossrail. Working on the formative period of the Lower Lea Valley and other large regeneration projects spurred his interest in thoughtfully integrating ground engineering and other delivery-focused disciplines into masterplanning processes, blended with his earlier exposure to the emerging approaches to masterplanning of underground space in Hong Kong in recent decades. Since then he has been involved and further pursued several themes around underground space including the 50 year 3D masterplan for a major campus in Singapore, embedding consideration of use of underground space into various precinct scale pursuits, identification and application of relevant technology such as digital modelling and concepts in innovative re-use of existing underground space. He is a Chartered Fellow of both the Institute of Materials Minerals and Mining and the Geological Society.
